Mercedes-Benz 560SL Speaker FAQ
What speakers should I replace first in my Mercedes-Benz 560SL?
Replace the 4-inch dashboard speakers first. They handle most of your mid-range frequencies and vocals - basically everything you actually notice while driving. The dashboard location puts them closer to your ears, around 60-80 Hz to 20 kHz range typically. Rear deck speakers can wait. They're 4x6 inch coaxials but honestly, you probably won't hear much difference until the fronts are sorted. Dashboard replacement might require some trim removal though.
Can I upgrade the 4x6 rear speakers in my Mercedes-Benz 560SL to component speakers?
Stick with coaxial full-range speakers for the rear deck lid location. Component systems need separate tweeter mounting, and your 560SL wasn't designed for that back there. Look for 4x6 coaxials with around 50-90 watts RMS handling. The rear deck position works better for fill rather than imaging anyway. You'd need custom fabrication for components, and the improvement wouldn't justify the work. Maybe consider coaxials with better tweeters instead - silk dome or aluminum.
Why does my Mercedes-Benz 560SL have different sized speakers front and rear?
Space constraints mostly. The dashboard area limits you to 4-inch round speakers, while the rear deck can accommodate the larger 4x6 oval format. This creates an interesting setup - your fronts handle detail and imaging, rears provide some bass fill. The 4x6 speakers probably move more air for lower frequencies, maybe down to 50-60 Hz depending on the model. Not ideal for perfect sound staging, but it works within the 560SL's design limitations. Could always add a small subwoofer later.
What impedance should I look for when replacing Mercedes-Benz 560SL speakers?
4-ohm speakers will work best with your factory amplifier setup. Most aftermarket car speakers run 4 ohms anyway, so you shouldn't have trouble finding replacements. Both the 4-inch dashboard and 4x6 rear deck speakers should match this impedance. Using 8-ohm speakers might reduce your volume levels, though it won't damage anything. The 560SL's electrical system can handle the load either way, but 4-ohm gives you better power transfer from whatever amplifier you're running.
